In the normal heart, There Are Four Separate chambers, the two top chambers Are Knownatria and pump blood as Simultaneously Into The two bottom chambers, or ventricle. Blood first Unbreak the heart at the right atrium, Which Then blood empties Into the right ventricle s, which pumps the blood Into the Lungs-through the pulmonary artery to get oxygen. From the lungs, the blood Enters the left pulmonary vein Through the atrium, the left atrium empties Into the left ventricle s, which pumps the blood Into the aorta and From There Reach the rest of the body. Because it is responsible for getting blood to the Entire body-through the aorta, the left ventricle is the Biggest and Strongest Usually chamber of the heart.
The Following is a depiction of normal blood flow-through the body. Valves keep the blood from flowing backwards. Capital letters Indicate tha blood from both ventricles instead of just from the left (overriding aorta), a defective right ventricular outflow tract near the pulmonary valve that prevents full flow of blood to the lungs, and a muscular right ventricle necessary to accomplish the extra work required to overcome that defect (right ventricular hypertrophy).
The following is a depiction of blood flow in Tetralogy of Fallot. Mixed capital letters indicate partially oxygenated blood.
